Valve.



, invented a certain new and useful Valve, of I which the following is a full,elcar, and exact description.

. iilators, and has for an object to provide a valve to regulate the floiv of liquids and i iuore particularly to regulate the flow of i water from one reservoir to another.

a easing having an inlet and' an outlet and 1,013,866. VALVE. Jaiuns (lou, l aha1a, llaivaii. Filed Apr. 22, 1910. Serial No. naomi.

To all whom it may concern.'

lie it known that I, JAMES Omi, :i subject ot the King of Great Britain, aud a. resident of lahala, Kan, Territory of llawaii, have My invention relates to luid pressure reg- For the purpose mentioned use is made of provided with means engaging the casing to regulate the How of water passed through the casing, the said means being preferably spring controlled and so constructed that; when the valve is in operation the water or: other liquid will at all times act against the said means to hold the valve in closed position.

Reference is to be had to the accompanying drawings forming a part of this specification. in which similar characters of reference denote corresponding parts in all the views. and in which- Figure 1 is a sectional side view vof a [lushing ap aratiis erLuipped with my valve, parts o the same eing broken away to disclose the underlying structure; Fig. 2 is a Sectional side view of niv valve showing the same in normal or closed position. Fig. 3 is a sectional view taken on the line 3-3 in Fig. 2; and Fig. 4 is a fra nientary sectional view showing a modified orin of controlling means to open or close thevalve.

Before proceeding to a more detailed description of my valve, I wish it understood that iiiy valve possesses several features inI the construction and operation of valves, iiotj shown or applied to valves most generally used at the present time. In the ordinaryi type of valve the water in most cases aetsj with the valve or means for operating thei valve, to open the saine. In uiy iinprovedl type of valve, the water pressure is utilizedl to act against the valve or controllingmeanmf so that when the valve is to he opened it must he opened against the water pressure. In this manner leaky valves are avoided: and the pressure against the valve can be still further increased by the addition of ay spring adapted to press the valve more c oselv against the valve scat.

Re erring more particularly to the various views, I provide n casing 10, having an inlet opening 11, st right angles to the cas-V irg 10, and an outlet opening 12 at one end o the casing. For t e purpose of more i fully describing the operation of niy valve I tluive shown the saine disposed in a flush tank 13, and having the inlet l1 connected with a supply pipe 14, as will be seen by referring to Fig. 1. Screw-threadedly secured to the upper end of the easing 10 is a hexagonal cap 15, having formed thereili centi-:illy disposed chambers 16 and 1T. .\4 valve chamber 18 is provided in the easing l0. and at the upper eiid thereof is formed a valve seat 19. Normally disposed oii thi` valve sent 1) is a valve 20, plovided with a valve stein 2l, preferably triangular iii sha pe and extending doiviiwardlythrough the valve ehnuiher 18. A guiding .valve stem 1 22 is also provided on the valve 2O and exi tends upwardly into the chamber 16 of the leap 15, and a spring 23, is disposed to encirclev the guiding stem 22 and extends into the chamber 17 of the cap 15. An opening 24, isprovided at the lower end of the casing 10, and pivotally mounted in the casini*T 10 and adapted to extend outwardly throng i the opening 24, is a lever 25, adapted to engage the valve stem 21 when the valve 20 1s to he opened. A hall or Heat 26, is secured to au end of the lever 25, the size of the float 26 or the length of the lever 25, being proportional to the amount of pressure acting against the valve 20, or proportional to the force required to lift the valve 2O from the valve seat 19. Connected to suitable levers 27 and 2", mounted by means of a hanger 28, `on the tank 13, is a valve 29, controlling an outlet ipe 30, and the valve 29 is operated hy pul ing or releasing a cord 31 depending from the lever 27. y Suppose the tank 13 to be filled with water; the float. 2G will tend to move toward the surface of the water and the lever 25 will he in the position shown in Fig. 2, and out of ;engagement with the valve stem 21. Now h v pulling the cord 31 the valve 29 is opened and the wateii rushes out through the pipe 30. As the water level in the tank 13 hej comes lower, the float 26 moves downwardly iand the lever 25 is caused to engaoe the valve stem 21, as will be seen by referring to Fig. 1. When all the water is draivn l from the tank 13. the weight of the float 26 i will cai-ry the same to the floor of the tank Eand the valve 20 will be raised from the valve sent 19, as can also be clearly seen hy referi'iiig to Fig. 1. Noiv the supply pipe [14 is filled with water and opens iiito the easing l0, so that when the valve 20 is raised agaiust the water pressure in the supply i pipe and the pressure of the spring 28, the g water in the supply pipe rushes through the valve opening and the outlet 12 into the 1 tank 13. As the water enters the tank 13 n nd commences to till the same, the oat 26 rises with the water, and when the tank is full the height of the toat causes the lever lcs/Bree 25 to be tilted at au angie :mu veic-ase me; valve stem 2lt thus returning tho valve QOi to closed position. The vulve 29 in the tank 13 operates partly by the water pressure in'f the tank, so that when the valve is openod the water in the tank holds it open untih the water hns left the tank 13, when the' weight of the valve causes the same to retura to closed position nml the valve can only he re-opened by pulling the cord Il In Fig. 4 is shown a lnodilied form of my device, the valve in this casing being the same as hercinhel'ore described` but operated by a cani 32 mounted on a controlling stem 33, provided with a handle 34. 'lhis` modified forni is preferably adapted for faucets,

i especially for faucets where a heavy water pressure is to be controlled, and by turning.

i the handle 34 the cam 82 will be made to operate to engage .the valve stem 2l. and raise the valve 20 in the same manner as i liereinbefore described and shown.

It will be distinctly understood that` althou vh I have sh'own and described my valve main y as applied to lush tanks. the valve can be conveniently applied to various devices designed to he operated by valves, nml that I do not limit myself to the precise construction shown, the seo e of my invention being fully disclosed in t ic appended claims.

Ilaving thus described my invention, I claim as new and desire to secure by Iettcra Patent:
